A palladium(II)-catalysed intramolecular oxidative C–H/C–H cross-coupling of N′-methylenebenzohydrazides to phthalazin-1(2H)-ones has been developed. This cyclization is believed to mechanistically proceed via electrophilic ortho-palladation and subsequent C-arylation of the carbon–nitrogen double bond.
